libKISSlog is a trivial lightweight C++ template library designed and written according to the KISS (Keep It Simple and Straightforward) principle. It leans heavily on STL for keeping its implementation as simple as its usage, and tries to provide C++ developers with a lightweight, paradigm-pure, and flexible alternative to logging libraries which use design and/or implementation decisions which at least the author of libKISSlog believes to be questionable. Its easiest to explain why libKISSlog would be suitable for your needs by listing the things which libKISSlog does not choose to use or do: no singletons or other forms of mutable global state, no macros, no attempt to fit the Java runtime everything model onto a C++ library, no attempt to be a Java-style (bloated) framework, no attempt to make the choice for you of whether you need thread safety, and no compromise on simplicity in order to facilitate questionable inner-loop logging practices.

Simblog aims to be one of the most easy-to-use and lightweight blogging platforms. It emphasizes user experience, workflow, and ease of use without neglecting usability and extensibility. It will take full advantage of what HTML5 and CSS3 have to offer without delving too deeply into experimental features. It is built on its own lightweight framework, which allows a high degree of extensibility and modularity for your blog. It uses Smarty as a templating engine (which also provides a caching mechanism), jQuery and Kendo UI for frontend design, and MySQL as a database.

XPathAPI is a Java library which offers simple methods to select nodes on XML document trees using XPath expressions. These methods relieve you from writing many lines of repetitive code. With XPathAPI, many common tasks become simple one liners.
